Pilot Study of Corneal Clearance With the Use of a Rho-Kinase Inhibitor After Descemetorhexis Without Endothelial Keratoplasty for Fuchs Endothelial Corneal Dystrophy

Purpose: To investigate corneal clearance time using a topical rho-kinase inhibitor, netarsudil, after descemetorhexis without endothelial keratoplasty (DWEK). Methods: Twenty eyes from 10 patients with Fuchs endothelial corneal dystrophy had DWEK with cataract surgery. For the first eye of each participant, netarsudil was administered immediately after surgery until corneal clearance. For the second eye, netarsudil was withheld 2 weeks beyond the time for corneal clearance of the first eye and then administered only if corneal edema was still present. Interpatient and intrapatient comparisons were made for pachymetry, endothelial cell count, intraocular pressure, and time to corneal clearance. Results: Intrapatient comparison demonstrated no significant difference in preoperative pachymetry (P value 0.58), endothelial cell counts (P value 0.97), and intraocular pressure (P value 0.46) between eyes treated with netarsudil immediately after DWEK and those with delayed netarsudil use. Average time for corneal clearance in eyes treated with netarsudil immediately after surgery was 4.6 ± 1.7 weeks, which was significantly shorter than eyes not treated with netarsudil immediately at 8 ± 1.9 weeks (P
